MOVING OBJECT DETECTION METHOD

摘要

A moving object detection method according to an embodiment includes evaluating an average value, instead of a median value, of pixel values at the same pixel positions across multiple superposed images. A threshold value obtained by multiplying the average value by a predetermined number is employed to distinguish space debris from an object which emits light at a higher luminance than the space debris. In order to detect the space debris accurately, an average value of the pixel values that are equal to or less than the threshold is employed as an evaluation value for the space debris detection.

1. A method for detecting a moving object being an observation object from images captured in constant intervals, based on an evaluation value obtained from pixel values at the same pixel positions overlapping one another across the images by sequentially moving the images in accordance with a content corresponding to an estimated movement content of the moving object being the observation object during the constant intervals, comprising:
an average-value-of-limited-pixels calculating step of calculating an average value using pixel values which are equal to or less than a threshold value for distinguishing the moving object being the observation object from a light emitting element with a higher luminance than that of the moving object, the pixel values being among the pixel values at the same pixel positions across the images; and a judgment step of judging pixels at the same pixel positions across images, whose average values calculated in the average-value-of-limited-pixels calculating step are equal to or greater than a criterion value, as pixels capturing the moving object being the observation object, or capturing candidates for the moving object.
